Given that the rate of change of population of the bats in a certain state is 2.9%, means that after a year, the population will become 1.029 of the current population. The equation that would best represent the described scenario above is,
y = (270,000)(1.029^x)
Answer:
w=9z
Step-by-step explanation:
For each z value, w is 9 times that. For instance, 18 is 9 times 2, and 45 is 9 times 5. Therefore, the equation that would describe this is w=9z. Hope this helps!
X = Harry's Age
Nick's age is 7x
In 6 years Harry is 7x+6, and Nick is 5(x+6)
7x+6=5x+30
2x+6=30
2x = 24
x = 12
Harry = 12 years old and in 6 years Harry will be 18.
Answer: 180
